2004 s60 2.4D vibrating and weird start up

urban60 · Sep 13th, 2017, 09:50

Hello,

I own a 2004 s60 2.4D with 390.000 km. Recently, large servis was made with replacement of the following:

Oil
Oil filter
Fuel filter
Cabin filter
Serpentine belt + water pump + tensioner
Drive belt
Some kind of mount for gearbox or clutch (I've attached picture of it, because I'm not sure what is it)

Before servis, I've noticed some vibration (cabin, steering wheel and pedals) at 1500 RPM (1450 - 1550) but after servis, vibrations are more noticeable. These are most intensive in larger gears, but most noticeable in 3rd and 4th gear. There is also large resonating sound at 3000 RPM and above.

Picture of the mount:

Other thing is this weird start up which is present quite longer. I've found the video (attached bellow) of this guy who had the same symptoms. The thing is, that I've checked the glow plugs and only 2 of them were working, so I've changed all of them but the problem is still there. I was also skeptical about the glow plugs, because motor had start up issues whole summer (at 30°C/90°F).

Does anyone have some sort of idea what could be wrong?

Posted mount is not OEM part. Could that be the reason for vibrations?

Does the car start easily when cold. Difficult or long cranking for cold starting is usually a sign of one or more leaky injectors. A leak back test would show if there is a bad one. Max leak about 40 cc per minute at idle.
I would have a look at your auxiliary belt when the motor is running. Have an assistant raise the revs to 1500 and see if the belt tensioner is moving a lot. This could be a sign of failed alternator pulley clutch.
Take off the alternator belt and see if the noise remains.
These cars do not need the glow plugs to start if the ambient temperature is at 7 C or above.
many have found them defective and replaced them to no effect.

Thank you for your advice. I will definitely check the injectors, because I don't know when they were last checked/replaced.

Considering vibrations... I have to update you, that there are no vibrations in idle and when revving the engine in neutral, but I've noticed there are vibrations when putting it to neutral (at 130 km/h) after driving few kilometers on the motorway. But those vibrations stop reaching smaller speeds. As I said, vibrations at 1500 RPM are the most noticable in 2nd, 3rd and 4th gears. Could this also be problem of injectors?
